Tansy bee

Description:

According to Kenn Kaufman's guide... They are generally small to medium-sized. The family exhibits behaviors ranging from solitary to semisocial. Nests are burrows in the soil or sometimes rotting wood. Over 500 species range north of Mexico. Species of Halictus often resemble, Andrena, typically with a banded abdomen. All known species nest in soil. Most exhibit some degree of sociality, the usual pattern being for daughters to remain with their mother, expanding the nest and helping to rear additional generations of her offspring throughout the nesting season. Males are normally produced as part of the last generation, in late summer or fall.

Notes:

I found several pollinators, and will look up species after posting. But if you know, let me know. It is on a daisy that is about 1.5 inches wide.
